Welcome Leighla!
I am also a planner and organizer. (I analyze things all to pieces!

) My advice is to take some time to research and plot, create a master strategy, and set a date when you're going to begin it all. I started planning in mid-April, incorporated the changes in a little bit at a time, and my official This Is The Beginning day is tomorrow. (Oh, and be prepared to have to tweak...no plan is foolproof.)
3FC is a great place for support. I can't believe how active the forum is and how encouraging and helpful everyone is. You've come to the right place.
Good luck! You CAN do it.
